In the past few years, diversification has turned into a highly controversial issue amongst numerous managers in almost each and every business. It is contended by many that diversification is vitally important and highly effective especially when it comes to evaluating the financial performance. There are several studies about the relationship between diversification and financial performance. However, there is no agreement that diversified firms are more efficient than focus firms. In this paper, the manufacturing firms listed in Bursa Malaysia are ranked based on their efficiency scores calculating by Data Envelopment Analysis (DEA) models and the effect of diversification on the efficiency scores of these corporations have been investigated. Moreover, by slack analysis, the proposed improvement strategies for inefficient firms have been cited. Ultimately, the Malmquist index of productivity (MIP) has been utilized to further comparison and analysis.

There is little consensus on the corporate diversification-efficiency relationship in the diversification literature. According to the corporate diversification, firms have a tendency to get more market share with diversifying in the local segment or in the international market. Theoretically, a contradictory exists between the profitable strategy and the value reducing strategy in the diversification strategy. In this paper, we measure firm’s efficiency by applying Data Envelopment Analysis (DEA) in manufacturing firms listed in Bursa Malaysia for five years. Meanwhile, a feed forward multilayer perceptron neural network is applied to model the mapping function between the input and output data to the efficiency score. Back propagation (BP) learning algorithm is applied to update network’s weights through minimizing the cost function, and the best topology of the network is conducted. The result of this study shows that there is a negative relationship between total product diversification and efficiency, and international diversification has a non-linear effect on the efficiency.
